Now we build only what we really need for 'build' platform - there is
new build-tools make target.
The list of tools is in solenv/gbuild/extensions/pre_BuildTools.mk.
Also similar is done to some extent for 'host' platform using
gb_Module_add_targets_for_build which is ignored for 'host'.

Always link in gb_STDLIBS, except when the library explicitly opts out
with gb_LinkTarget_disable_standard_system_libs.

Naming convention for gbuild methods:
- "add" is used for stuff that is logically a part of the target
(i.e. not registered at the Module, but defined in the target's makefile)
- "use" is used for stuff that is logically a different target
(i.e. it is registered at the Module, has it's own makefile, may be
in a different module than the target)
